As thusv far described, the structure corresponds substantially with that covered in prior Patent No. 708,747 of September 9, 1902. Secured to the rod 7 .is afo'rked crosshe'ad 8 havinga central rccasting. f1. A 'ha'nd le 12 oiitsi(le' of tliecasting 11 is operativelynconnected to said shaft 1'1.

p 10 mounted i'i'zckerarin 14 hav ng a r face 17 of the portion 2 andan arm 18 adapt toengage either with a lever 19 or lever 27 carried-by the "shaft 11} and preferably cast integral with the don-.j

ble cam device '10. Theinetnber'idhas a centrally arranged recess --f or :;'a spring 20 -wh ich is coiled around the pivot pin 21 of the rocker arm ,14 and""has -one end -in;en= gage'ment with the toe 16 and the other end 1n engagement with-a projection or stop-22 on the casting}. The pressure ofthe spring "*20 tends to rotate the rocker arm 14 so as to engage. either 'withthe leverj 19 or the lever 27 and turn the'same with the shaft 11 to the normal locking position. I g 1 In operation, when two coupler heads are brought together, the inclined face 17 of the projection '21of one coupler head engages the toe -16 of, arm 14 on the counterpart A position shown 'in, Fig; 3, against the rehead andini the movement to the coupled position, forces'the rocker arm 14 to the sistance of spring 20. In order to uncouple, the operating .lever'12 is 'turnedso that the roller 9 is forced outwardly by oneof the pro'ecting portions and thereby the rod 7 I shi ts the lever 6 to its uncouplmg position,

"as shown in Fig. 3. The coupler heads are now free to-se aratewhen the cars are pulled apart an as the inclined face '17 of the projection 2 moves away, the toe 16 can move outwardly and the rocker arm 14 is thereupon rotated by the spring 20 to turn the lever 19 andthereby the shaft 11. The rotation of cam 10 throws the roller-Shout of its locking engagement with said cam and the spring 13 acting on the rod 7 is then permitted to complete the full movementof the locking device to its normal locking position, in readiness for again coupling up. It

will now be evident that with my nnprovement it is not necessary for theoperat'orto set the operating levers of the coupler heads back to the lockin position, as this operation is automatical y accomplished as above described.

. According the form of my improve-i ment illustrated in Figs. 5 to 8 of the -dra wings, the spring 20- may be dispensed.,w1tl1.

and the tripping device positively operated .by the direct action of thecoupler heads 7 A separating. As well understood, with this the same function as the knuckles of-the 55 type of .coupler,'the projections v5 perform ordinary car coupler, and in theact of'uncoupling afterthe locking levers are released, as the cars separate, thepro ection 5 on each head moves laterally on the ooacting inclined face of the projection 5 of the counterpart coupler head. J This lateral movement of the coupler head is employed, in the form of my improvement now to be described, for operating the tripping device. Accordingly, the projecting portion 2 of the coupler head is provided with a ca trally arranged notch or recess 25, within whichthe end of lever 15 carried by the rockerarm Mis adapted'to rest when the coupler heads are lockedftogether. V The other lever 18 of the rocker arm 14 is adapted to engage either with an arm-19' similar to arm 19 of the construction hereinbeforedescribed or with arm 27 V.-

In operation, the handle 12 having been operated to shift the locking device 6 to the uncoupling position, as shown in Fig. 7 when the cam are separated, the-projections 5 ofthe'cou )ler heads move'laterally as well as longitudlnally and the end of the lever 15 engaging the longitudinal face 26 of the recess 25, is shifted and thereby the lever 18 acts on the arm 19' to shiftthe same toward the normal locking position, as

shown in .Fig. '8. The arm'19' having been thus partially rotated, theffull movement of the lockin deviceto the normal locking po-i sition is efi'ected by thespring 13, as in the previously described construction. It will be understood that in case the handle is turnedfin the opposite direction so that theother projection of; thecam IOengages the roller 9 instead-of the one shown in Figs; 3 and V7,.then the movement vof-the rocker arm operates to rotate the shaft 11 through either the lever 27 or lever ,27 according to which construction is employed, In theconstruction shown, in Fi s. 5 to'8 inclusive where the spring 20 is dispensed with, the

rocker arm '14- is shifted into position in hooked portion adapted to engage a similar portion of a'counterpart coupling, a locking lever for clamping said members to gather laterally, a spring tendingto move said lever tothe locking positiom a-cam for, shifting said locking lever to and holding same in itsunlockedposition to permit uncoupling. and a rocker arm'mfengagement with said camandadapted to move upon withdrawal of the counterpart coup ing fromthe coupled-position and thereby trip said cam out of the -unlocked position to permit said spring toshift the lockinglever to the locking position;
